"I've heavily reasearched premium 'diet' kibble brands. C&P is really the only one that has managed to cut calories significantly while maintaining a high meat and protein content. The fourth ingredient is barley, a good quality grain - oat groats and potatoes are also good quality ingredients. NO corn or wheat, both of which have low digestibility and often cause allergy problems.
On the negative side, the third ingredient and major grain in the food is brewers rice. This is a very low quality grain and a by-product of the brewing industry. Sorghum is a grain with low digestibility. Fermentation solubles are a byproduct and have no nutritive value.
A decent quality food, but would be an excellent one with a few ingredient changes."
